Abstract

A protocol chip transmits the request from the host apparatus to a first processor through a first address translation unit. A first processor transmits a response to the request from the host apparatus, to the protocol chip through the first address translation unit. When the first processor stops processing, an instruction to transmit the request from the host apparatus to a second processor is transmitted to the protocol chip. When receiving the instruction to transmit the request from the host apparatus to the second processor, the protocol chip transmits the request from the host apparatus to the second processor through a second address translation unit. The second processor transmits the response to the request from the host apparatus to the protocol chip through the second address translation unit.

Abstract

Each controller of a plurality of storage controllers is an old storage controller before replacement or a new storage controller after replacement. The new storage controller can execute a first program and a second program, and the old storage controller can execute at least the second program. When all of the plurality of storage controllers are the new storage controller, the new storage controller processes data input and output to and from the storage drive by using the first program. When the plurality of storage controllers includes at least one of the old storage controllers, each storage controller of the plurality of storage controllers processes the data input and output to and from the storage drive by using the second program.

Abstract

In failover processing, a CPU restores data stored in a first volume to a second volume of a storage system, associates a unique ID of the first volume with the second volume, and stores the unique ID associated therewith in a memory. After the failover processing is completed, the CPU manages an update difference management bitmap indicating an updated content with respect to data stored in the second volume. The CPU transmits, in failback processing, update data updated after the failover processing among the data stored in the second volume to the first volume identified by the unique ID associated with the second volume based on the update difference management bitmap.

The CPU receives target performance information that indicates target performance for the program, calculates per site a necessary allocation amount and a necessary electric power consumption amount that are a resource allocation amount and an electric power consumption amount necessary for realizing the target performance by using the target performance information, the performance model, and the electric power consumption model, and creates a container/data allocation plan that is an allocation plan of an execution platform of the program and data based on a result of the calculation.
